On Moduli Stabilisation and de Sitter Vacua in MSSM Heterotic Orbifolds
Susha L. Parameswaran, Saul Ramos-Sanchez, Ivonne Zavala
We study the problem of moduli stabilisation in explicit heterotic orbifold compactifications, whose spectra contain the MSSM plus some vector-like exotics that can be decoupled. C…
Lifshitz solutions in supergravity and string theory
Ruth Gregory, Susha L. Parameswaran, Gianmassimo Tasinato +1
We derive Lifshitz configurations in string theory for general dynamical exponents z \geq 1. We begin by obtaining simple Li x Omega solutions to supergravities in diverse dimensio…
Non-standard primordial fluctuations and nongaussianity in string inflation
C. P. Burgess, M. Cicoli, M. Gomez-Reino +3
Inflationary scenarios in string theory often involve a large number of light scalar fields, whose presence can enrich the post-inflationary evolution of primordial fluctuations ge…
The effect of extra dimensions on gravity wave bursts from cosmic string cusps
Eimear O'Callaghan, Sarah Chadburn, Ghazal Geshnizjani +2
We explore the kinematical effect of having extra dimensions on the gravity wave emission from cosmic strings. Additional dimensions both round off cusps, and reduce the probabilit…
Effect of extra dimensions on gravitational waves from cosmic strings
Eimear O'Callaghan, Sarah Chadburn, Ghazal Geshnizjani +2
We show how taking into account the kinematical effect of extra dimensions can have a significant impact on the gravity wave emission from cosmic strings. Additional dimensions bot…
